WWII Β· War Crimes & Atrocities

The Darkest Hours

World War II produced atrocities on a scale and with a systematic deliberateness that exceeded any previous conflict in recorded history. Nazi Germany's genocidal program murdered approximately 11 million people in industrialized killing centers; Imperial Japan conducted biological experiments on living prisoners, massacred civilian populations across Asia, and subjected prisoners of war to conditions that killed hundreds of thousands. Even the Allied powers committed atrocities β€” the Soviet massacre of Polish officers at Katyn, and the Allied firebombing of civilian population centers β€” that complicate any simple moral narrative. The war's atrocities produced the legal frameworks of the postwar world: the Nuremberg Principles, the Genocide Convention, and the Universal Declaration of Human Rights.
